Dem 29, 1931. R. H. SCHWARTZ WINDOW CLEANER Filed March 22, 1930Patented Dec. 29, 1931 UNITED STATES PATENT OFFICE wmnow CLEANERApplication filed March 22, 1930. Serial N0. 138,105.

This invention relates t wipers 01 squeegees and is specifically adapted1501 use by service station attendants for cleaning the windshields ofthe auto1nobiles of patrons Wh0 drive in for gasoline,oil 01 otherservicing.

One 0f the objects of this invention is 130 provide a wiper or squeegeewhich 1nay be handily carried around in the pocket of a garment er theside pocket 0f an automobile.

Another object is to provide a wiper which is so economic of manufacturethat it can be used as a give .away article for advertising purposes.

Another objeet is to provide a wiper which is durable and efficient inuse.

Olher objects and advantages 0f the i1nproved windshield cleaner W1llappear as the des'cription proceeds.

Referring 110W to the drawings:

1g. 1 is a plan view 0f the invention ready f0r use.

Fig. 2 is a similar view with the handle folded for convenient carrying;and

Figs. 3, 4, 5, and 6 are views, respeetively 011 the lines 33 44l, 55and 6-0 of Fig. l, all taken in the directions indicated by the arrows.

Referring now more in detail t0 the draw- 110 ings the body of the wiperis c0n1posed 0f a channel 1ne1nber 10 for holding the wiping ele1nent11. This wiping element is preferably 0f wedge-shaped CIOSSSQCOII asclearly shown in Flgs. 4 and 5 and is preferably made of rubber 01si1nilar material. By 1naking the wiper ele1nenl; 01 Wedge shapedcross-section, a flexible wiping edge is 0btained t0 eflectively wipetl1e parts being cleaned and a thickened base portion is 0btained whichprevents early breaking o1 tearing of the wiper element along a linedefined by the edges of the channel holding the wiper element, as is thecase in the ordinary 001'1- struetion 0f wiper.

The sides of the channel member 10 are bent toward each other, as shownin Fig. 5, 130 finnly grasp and hold the wiper element 11 fron1 points12 nea1 the Center of the channel t0 the ende thereof, the centralportion 0f the channel being left With the sides there- 0f substantiallyparallel, as shown in F igs. 3 and 4. T0 this portion of the channel ispivotally attached by means of a riv et, 01 othe1 suitzible securingmeans 14 the channel shaped handle 15. The upper end of the handle isferked as at 16 t0 receive ehe channel me1nber 10 therebetween. Thebottom of the channel, adjacent the forked end, at ics end edge 17, actsas a stop t0 li1nit the pivotal movement 0f th-e handle 15, when thesa1ne is being opened, by engaging the botto1n 0I the wiper retainingchannel 10, This edge 17 is so located as to stop the handle when ltreaches a position substantially perpendieular to the body of the wiper.

lVhen not in use the channel shaped handle 15 is 1"0lded 011 t0 the b0dy0f the wiper as shown in Fig. 2 and can be conveniently eatried in apocket 0f a gannent and ean be quickly reaehed when it is desired to usethe same.

In order to hold the handle in its folded position When not in uses1nall depressions 18 are made in the lege of the channeled handle nearthe top thereof for engage1nent with ehe parallel sides 16 013 theCenter 01 the channel 10. lt will be evident that this engagement of thedepressions 18 against the sides 16 Will act as an eflicient 1neans f01holding the handle in folded position by virtue of the inherent springaction that Will be in the opposink sides of the channeled handle 15 andby Virtue of the rivet holding the sides thereof against the sides 0fthe central portion 0f the channel 10.

lt Will thus be SGGI1 that a Wiping and cleaning device has beenprovided that is not only durable and eonvenient for carrying in apocket of a garment 01 side pocket 0f an autornobile but one Which issimple in 0011- struction and economic ef manufacc-ure. Al though aprefened embodirnent 0f the invention has been described it is so beunderstood that variations ancl modifications 1nay be resorted to whichfall within the scope 0f the appended claims.

Having thus deseribed the invention what is clai1ned and desi1ed to besecured by letters patent is:

1. A squeegee of the dass described having a wiping element ofwedge-shaped cross-section, a channel, the ends of which have couvergingsides for holding said wiping element and the central portion of Whichhas substantially parallel sides, a channeled handle pivotally attachedto the central portion of said channel, 1neans f0r holding a part 0f thebody 0f t he wiper within said channeled handle, and means for li1nitingthe pivotal movement of the handle, when being rotated to open position.

2. A squeegee of the dass described having a wiping element ofwedge-shaped crosssection, a channel, the ends of which have convergingsides ilor holding said Wiping element and the central portion of whichhas substantially parallel sides a channeled handle pivotally attached*a0 the eentral portion of said ehannel, depressions 011 the upper end0f said handle f01 engaging the central portion of said fi1st namedchannel me1nber and holding the pars in folded position and 1neans forlimiting the pivotal movement cf the handle, when being rotat-ed t0 openposition.

3. A squeegee of the dass described having a wipinp; element 0l' wedgeshaped cross section, a channel, means for securing said wiping elementwithin said channel, a channeled handle pivotally attached t0 thecentral p01 tlon olt said channel, means for holding a part 0f t-he bodyof the wiper within said channeled handle and 1neans for limitin thepiv- 0tal 1n0ve1nent 0f ehe handle, when being rotated to open osition.

l. A squeegee of the dass described comprising a channel, a wipingelement secured in said channel, a channeled handle pfvotally attachedto the central portion 0f said channel, depressions 011 the upper end ofsaid handle f01 engaging the central ortion Of said first na1ned ehannel1nember and holding the parts in folded position and means .f01'limiting the pivotal movement 0f the handle when being rotated to 0penposition.

5. A. squeegee 0f the dass described having a wiping element, a channel,the ends 0f which have converglng sides f01 holding said wiping elementand the central portion of which has substant-ially parallel sides, achanneled handle pivotally attached to the central portion 0f saidchanne], means f0r holding a part of the body 0f the wiper within saidchanneled handle, and means f01 li1nitlng Ehe pivotal movement 01. thehandle when being rotat'ed to open position.

In testimony whereof I hereunto aflix 111 signature this 20th day ofMarch, 1930.
